Fortinet Breach Incident Score: Analysis & Impact (FOR0562105111925)

In this Rankiteo incident briefing, we review the Fortinet breach identified under incident ID FOR0562105111925.

The analysis begins with a detailed overview of Fortinet's information like the linkedin page: https://www.linkedin.com/company/fortinet, the number of followers: 1167752, the industry type: Computer and Network Security and the number of employees: 15505 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 637 and after the incident was 621 with a difference of -16 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Fortinet and their customers.

On 18 November 2024, Fortinet disclosed Vulnerability Exploitation, Command Injection and Zero-Day issues under the banner "Exploited Command Injection Zero-Day in Fortinet FortiWeb Firewall Products (CVE-2025-58034)".

A command injection zero-day vulnerability (CVE-2025-58034) in Fortinet’s FortiWeb firewall products is being actively exploited in the wild.

The disruption is felt across the environment, affecting FortiWeb Firewall Products (versions 7.6.0–7.6.4, 7.4.0–7.4.8, 7.2.0–7.2.11, 7.0.2–7.0.11).

In response, and began remediation that includes CISA added to Known Exploited Vulnerabilities Catalog and Fortinet likely working on patches (not explicitly stated), and stakeholders are being briefed through Public advisory by FortiGuard Labs and CISA advisory issued.

The case underscores how Ongoing (exploitation confirmed, patches likely in development), and recommending next steps like Apply patches for FortiWeb versions 7.6.0–7.6.4, 7.4.0–7.4.8, 7.2.0–7.2.11, 7.0.2–7.0.11 once available, Monitor for signs of exploitation (e.g., unusual CLI/HTTP requests) and Follow CISA guidance for federal enterprise mitigation, with advisories going out to stakeholders covering CISA advisory for federal enterprises.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Valid Accounts: Local Accounts (T1078.003) with high confidence (95%), supported by evidence indicating authenticated attacker to execute arbitrary malicious code via crafted CLI commands and Exploit Public-Facing Application (T1190) with high confidence (95%), with evidence including command injection zero-day vulnerability (CVE-2025-58034) in Fortinet’s FortiWeb firewall products, and crafted CLI commands or HTTP requests. Under the Execution tactic, the analysis identified Command and Scripting Interpreter: Unix Shell (T1059.004) with high confidence (90%), with evidence including command injection zero-day vulnerability, and execute arbitrary malicious code via crafted CLI commands and Command and Scripting Interpreter: Windows Command Shell (T1059.003) with moderate to high confidence (70%), supported by evidence indicating execute arbitrary malicious code via crafted CLI commands (potential cross-platform impact). Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (85%), supported by evidence indicating authenticated attacker to execute arbitrary malicious code (implies elevated privileges via exploit). Under the Defense Evasion tactic, the analysis identified Masquerading (T1036) with moderate to high confidence (80%), supported by evidence indicating crafted CLI commands or HTTP requests (may blend in with legitimate admin activity). Under the Lateral Movement tactic, the analysis identified Remote Services: SSH (T1021.004) with moderate to high confidence (70%), supported by evidence indicating potential unauthorized code execution and risk to federal enterprise systems (implies post-exploitation movement). Under the Impact tactic, the analysis identified Endpoint Denial of Service: Application or System Exploitation (T1499.004) with moderate to high confidence (75%), supported by evidence indicating potential unauthorized code execution and service disruption and Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating follow-on attacks like data exfiltration or service disruption (theoretical, no confirmed ransomware). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
